Hi all! Is it possible for anyone to post pictures of their Bsa wm20 restoration process? Pictures can sometimes tell a lot more than a long explanation.So if...
Hi all, Has anybody fitted an on/off tap under the oil tank in order to prevent wet-sumping ? If so, what make and where did you buy it from please ? Cheers !...
Hi, Don't fit a tap under the oiltank, you will forget about it one day. Get yourself an anti drain valve from Bri Ti, this will cost you about 30 pounds but...

Many thanks for the 'ballpoint pen' advice. I will have some 1/4" diameter ball bearings so will have a try at replacing the ball and spring. Regards, ...
Brian, I have been monitoring the responses to your question. Firstly I wholeheartedly agree that it would be very unwise to fit an off tap in the oil line. ...
Hi, I don't agree with the ball and spring story, this is just the answer to a tiny problem in this story. If you look at the engine drawings you can see that...

BSW/ ME thread bolts Does anyone know where I can buy very small bolts. These are 1/8 wide and 1/8 long and 40 TPI. They are used to hold the horn and dip...
I'm sick and tired of playing with the generator on my 1942 M-20. Does anyone know where (on the East coast USA) I can get a rebuild or some help. Thank God...
Hi, Dont know if this helps. I know a guy in the UK who rebuilds them for about Ģ90. He did the one on my M20 and I have had no problems since. I had two...

Hi All Has anyone run an M21 on a 376 monoblock carb as I an unable to find the correct jet sizes for the idle and main jet or the slide no.I will be grateful...
I assume the M21 runs on a 276 like an M20? When I have had to put alternate carbs on a bike I always talk to hitchcocks as they have the conversion tables. ...
... Andy, The bolts you are reffering to are BA not BSW and from memory they are 2BA. Depending upon where you live BA bolts should not be a problem they are...

Hi Sacha, Welcome to the world of BSA. The difference between an M20 and an M21 is in the flywheels from the crankshaft and the piston. The conrod is the same....
Hi Henk, thanks for your answer. Nice homepage. I did it know allready quite some time ago. M20/M21: There is no barrel, zylinder, no carburator on/in the...
Hi Sacha, It should be possible to measure the stroke by rotating the engine and see how far the conrod travels up and down and see if it's a 600 cc or a 500...
Hi Henk, I think this is the only way to find out for the stroke. I checked yesterday again, the number on the motor is not WM21 but a BM21, sorry. is that...
Hi Sacha, If it's BM21 it's a post war engine, unfortunately not as rare as a WM21 engine. I don't think there are any BSF nuts and bolts on an English bike...
